Cant make DC, but can join domain.

I have a memeber server that has joined my AD domain, but when I try to make it a Domain controller I get the error message that: The wizard canot gain access to the list of domains in the forest. The error is: The specified domain does not exist orcannot be contatced.

I formated the PC and started over. I can become a memeber of the doamin fine and access the rest of the domain, just not become a DC. This server has 2 NIC's and wioll be used as a gateway.

Cant make DC, but can join domain.

According to Technet article Active Directory Communication Fails on Multihomed Domain Controllers (Q272294):"This issue can occur if one of the network adapters is attached to an external network (such as the Internet) on the multihomed domain controller, and if Lightweight Directory Access Protocol (LDAP) and Kerberos traffic between the internal and external networks is partially or completely restricted because of a Proxy, ISA Server, NAT Server or another firewall device.

In this scenario, network adapters on the multihomed domain controllers are registering both the inside and outside Internet Protocol (IP) addresses with the DNS server. DNS name resolution lookup requests return records in a "round robin" fashion, alternating the internal and external IP addresses. Replication operations require multiple lookup requests of SRV records. In this case, half of the DNS lookup requests return an IP address that cannot be contacted, and the replication operation fails."
